Moses and Aaron sent spies to check out Cannan.
They sent them so that they could learn how the enemy lived and what their strengths and/or weaknesses were. They didn’t plan on facing the battle unprepared.
We could learn from them.
Recognize what Satan could use to attack you: lies, jealousy, idleness, pity, fear, etc. If you deal with these know that they aren’t of the Lord. Realize that you are in a battle that needs to be fought and won.
The best warriors don’t just happen upon a win. They recognize the enemy and devote themselves completely to winning the fight.
